Have you seen the neighborhoods and people that live in "affordable" housing? No you wouldn't want to live there.
It seemed perfectly fine. I never went in, but the outside was clean, well lit, and well maintained. My neighbors there were just like my neighbors anywhere else on the block.
There's certainly a lot of bad public housing in the us, but that's not an immutable quality of public housing, that's a policy choice made by politicians.
What a disgusting comment.
Edit: I'm not saying that there aren't smart ways to do this, and converting one single-family lot in SF to a duplex certainly doesn't destroy the neighborhood. I am saying that some people have seen things they don't want in their backyard, and some people haven't.
